含NbSe2的铜基电接触复合材料的制备及其真空摩擦学性能研究
Preparation and Tribological Behavior of Cu-based Electrical Contact Composite Containing NbSe2in Vacuum
摘要
Abstract
Cu-graphite self-lubrication composite containing nano NbSe2 (0-9wt%) was fabricated by powder metal-lurgy technology. Friction property of the sample was investigated using micro-tribometer and ultra-low-temperature tri-bometer under atmosphere and vacuum conditions. The microstructure, phase and wear scar were also investigated by XRD and SEM. The results showed that tribological property was significantly improved after nano NbSe2 being added to the Cu-graphite self-lubrication composite. The composite with nano NbSe2 (5.5wt%) had smaller friction coefficient (μ=0.185) under vacuum dry friction conditions and higher carrying capacity than those of the composite without NbSe2. It was found that the wear could be attributed to adhesive wear together with contact fatigue wear.关键词
